Java compact3 javax.management Class MBeanNotificationInfo（JDK8）

Constructor Detail

• MBeanNotificationInfo

  public MBeanNotificationInfo(String[] notifTypes,
                               String name,
                               String description)

  Constructs an MBeanNotificationInfo object.

  Parameters:

  notifTypes - The array of strings (in dot notation) containing the notification types that the MBean may emit. This may be null with the same effect as a zero-length array.

  name - The fully qualified Java class name of the described notifications.

  description - A human readable description of the data.

• MBeanNotificationInfo

  public MBeanNotificationInfo(String[] notifTypes,
                               String name,
                               String description,
                               Descriptor descriptor)

  Constructs an MBeanNotificationInfo object.

  Parameters:

  notifTypes - The array of strings (in dot notation) containing the notification types that the MBean may emit. This may be null with the same effect as a zero-length array.

  name - The fully qualified Java class name of the described notifications.

  description - A human readable description of the data.

  descriptor - The descriptor for the notifications. This may be null which is equivalent to an empty descriptor.

Method Detail

• clone

  public Object clone()

  Returns a shallow clone of this instance. The clone is obtained by simply calling super.clone(), thus calling the default native shallow cloning mechanism implemented by Object.clone(). No deeper cloning of any internal field is made.

  Overrides:

  clone in class Object

  Returns:

  a clone of this instance.

  Cloneable

• getNotifTypes

  public String[] getNotifTypes()

  Returns the array of strings (in dot notation) containing the notification types that the MBean may emit.

  Returns:

  the array of strings. Changing the returned array has no effect on this MBeanNotificationInfo.

• toString

  public String toString()

  Description copied from class: Object
  Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

  The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

   getClass().getName() + '@' + Integer.toHexString(hashCode())
   

  Overrides:

  toString in class Object

  Returns:

  a string representation of the object.

• equals

  public boolean equals(Object o)

  Compare this MBeanNotificationInfo to another.

  Overrides:

  equals in class MBeanFeatureInfo

  Parameters:

  o - the object to compare to.

  Returns:

  true if and only if o is an MBeanNotificationInfo such that its MBeanFeatureInfo.getName(), MBeanFeatureInfo.getDescription(), MBeanFeatureInfo.getDescriptor(), and getNotifTypes() values are equal (not necessarily identical) to those of this MBeanNotificationInfo. Two notification type arrays are equal if their corresponding elements are equal. They are not equal if they have the same elements but in a different order.

• hashCode

  public int hashCode()

  Description copied from class: Object
  Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

  The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the Object.equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

  As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

  Overrides:

  hashCode in class MBeanFeatureInfo

  Returns:

  a hash code value for this object.
